The extravascular localization of tissue factor (TF), the central initiator of coagulation, is thought to ensure that thrombus formation is prevented in the intact vessel. We observed that during a 5-min stimulation of human blood with collagen (type I), TF antigen appeared on the surface of platelets adhering to leukocytes. The rapidly presented… (More)

INTRODUCTION
Neutrophil gelatinase-associated lipocalin (NGAL) is a powerful biomarker for the early detection of acute kidney injury. However, recent data suggest that NGAL also plays an important role in chronic kidney disease (CKD), reflecting the level of acute kidney damage within the CKD condition. To study whether elevated NGAL levels in CKD are a… (More)

OBJECTIVES
The clinical significance of anti-HLA-alloantibodies remains controversial. Recent studies have linked development of donor-specific HLA-antibodies to chronic allograft rejection and graft loss after heart, kidney, and lung transplants. We investigated the clinical impact of donor-specific humoral alloreactivity during the follow-up of heart… (More)

The diagnosis of thrombophilia caused by protein S deficiency remains difficult. From 2005 to 2010, we documented 135 patients with suspected hereditary protein S deficiency for whom mutational analysis of the PROS1 gene had been performed by direct double-stranded sequencing of the amplified 15 exons including splice sites. Multiplex ligation-dependent… (More)

BACKGROUND
The clinical relevance of the post-transplant presence of anti-major histocompatibility complex class I chain-related A (MICA) antibodies as a marker for chronic graft failure in heart transplantation was examined using post-transplant sera from 159 heart transplant recipients. Mean follow-up after transplantation was 7 +/- 4.9 years.
METHODS… (More)

BACKGROUND
The shortage of deceased donors led to an increase of living donor kidney (LDK) transplantations performed in the presence of donor-specific antibodies (DSA) or ABO incompatibility (ABOi) using various desensitization protocols.
METHODS
We herein analyzed 26 ABOi and 8 Luminex positive DSA patients who were successfully desensitized by… (More)

Allosensitization represents a major obstacle to successful re-transplantation since circulating antibodies can elicit antibody-mediated rejection episodes with subsequent graft failure. Since sensitization is primarily considered a contraindication to transplantation the duration for patients waiting for a suitable donor organ to become available is… (More)
